"american idol" finale, two "losts," three "24s," three and a half "law and orders." in this era with so many tv options it's not always just about the numbers. alex green sat through a four-day "lost" marathon. this is all pretty emotional for you. >> absolutely. >> what i made most of this week of endings was network television still matters. >> reporter: and with the internet and tivo, these shows, these characters, might go off the air but they will never die. well, except in "lost." they are dead, right? john berman, abc news, new york. >> kind of amazing to think a two and a half hour finale, that's what it was for "lost," people are still left going, what happened? pretty much what i thought of the whole show, though, i didn't get a lot of it.
